The strength of the spiral welded pipe is generally higher than
straight seam welded pipe . Larger diameter can be produced by
narrow black with spiral weld seam . We can also produce it with
different pipe diameter using the same width of black . But
compared with the same length of straight seam welded pipe , the
length of welding line increased 30-100% , and the production speed
is low . Therefore , relatively small diameter welded pipe are
mostly adopts the straight seam welded pipe , larger diameter
welded pipes are usually spiral welded pipe .
